  • Neither Cordova nor React Native is a native application and cannot compete with real native apps.
  • Since JavaScript is single threaded, we may have trouble running our React Native or Cordova application.

I have three years’ of experience as a JavaScript app developer and I am working both with React-Native and Cordova wrapper. And I once again concluded that there is no such thing as ‘the perfect…

Development Frameworks, PhoneGap and React Native make Mobile Application Development Easier

Native or Hybrid app for your business? #phonegap #mobileappdevelopmentindia #mobileapp.

  • Hybrid mobile applications are developed through web technologies, which includes HTML, CSS, and JavaScript and are hosted inside a native application that utilizes WebView.
  • So, with hybrid frameworks such as PhoneGap and React Native, developers are now finding it easier to create mobile applications that run anywhere irrespective of the device and platform.
  • A hybrid app development framework, PhoneGap / Apache Cordova can be easily extended through native plugins, thus allowing developers to add more functionality to the mobile application and enables to have access to the device’s camera, contacts, location, and much more.
  • With a hybrid framework, developers can create a single version of the mobile application and get it across multiple platforms within small time-frame and at a lesser cost.
  • Since hybrid mobile applications save data offline (through device API), the loading time is less compared to native and mobile web applications.

The increasing dependency on SmartPhones has enabled businesses to offer services through custom mobile applications and due to which the demand for mobile application developers

Frameworks Such as PhoneGap and React Native Ease Mobile App Development

  • Development frameworks such as PhoneGap and, more recently, React Native make it significantly easier for retail businesses to build and deploy mobile applications for consumers and internal teams.
  • First, developing mobile apps in each platform’s native language means that you need to have a few development specialists: a Swift developer for iOS, a C++ developer for Windows Mobile, and a Java developer for Android.
  • Another framework, Xamarin, takes this same approach, but uses the C++ language as its starting place, making it possible for developers accustomed to working with Microsoft applications to create a single application with all the capabilities of a native-language app, and deploy it across mobile operating systems.
  • PhoneGap, React Native, and other frameworks make developing a custom mobile app more accessible and relatively less expensive than developing in a specific mobile operating system’s native coding language.
  • Or those same in-house developers could build internal mobile apps to help the business operate without learning new programming languages or having to create different versions of the same application for each platform.

React Native Performance

#ReactNative performance and some tricks & tools to optimize your React Native application:

  • Every character typed in the Native component involves the physical event, transforms it in letter or action, and then transmits it by the bridge to the JS component.
  • In all of the transactions of data between JS and Native, the Bridge always intervenes so that the data is included in both parts.
  • The Animated library has been created to improve the performance of the animations, and its objective is to lighten the use of the bridge by sending predictions of the data to the native before starting the animation.
  • Thankfully, the Bridge isn’t the only one at fault, and there are many other ways to optimize a React Native application.Therefore, here is an exhaustive list of why and/or how you can optimize your application:

    The React Native “tooling” is not yet very developed, but a great part of the toolset is that itis coming from the application.

  • The performance of a React Native application is very important.

Pixel perfect cloud images in React Native – uncommon

Pixel perfect cloud images in React Native:  #ReactJS #JavaScript

  • It could simply define itself with a flex, like belowImage style={{flex: 1, backgroundColor: ‘red’}} resizeMode={‘cover’} source={{uri: /You could use Image component’s resize mode techniques to achieve the desired effect.Issue here is that you have not optimized image for exact screen resolution of the device.To do that, you need to generate a cloud url that includes dimensions of the image, which, is known only at runtime when Image layout is measured.
  • So you end up providing onLayout function to Image component, get those dimensions, generate a url and then finally re-render Image component with probably a state change in the parent component.You need to go through the same chore every time you would like to fetch an image from cloud service.
  • I will be using Cloudinary as image service provider, but the concept can be extended to any other cloud image service.CLImage component needs to track image width, image height.
  • Here is the snippet for renderImagerenderImage() { let opts = {} Object.assign(opts, this.props.options,{ width: this.state.imageWidth, height: this.state.imageHeight })return ( Image style={{ width: this.state.imageWidth, height: this.state.imageHeight }} source={{ uri: opts) }}/ )}And finally the placeholderrenderFreeForm() { return ( View style={[this.props.style, styles.background]} onLayout= {(event) = / )}Since React Native deals with device independent pixels, it is important to use PixelRatio to determine actual pixel size of the image.
  • This is how imageUrl function is going to look likeimageUrl(cloudId, options={}) { let opts = {} Object.assign(opts, {crop: “fill”, gravity: “face”, format: “jpg”, quality: 75, secure: true}, options) opts.width = opts.height = let url = cloudinary.url(cloudId, opts) console.log(“Image url is:” + url) return url}with CLImage component built, now I can use it to render cloud images with out explicitly specifying width/height, see belowView style={styles.mainContainer} CLImage cloudId={“sample_1”} / View CLImage cloudId={“sample_3”} / CLImage cloudId={“sample_4”} / CLImage cloudId={“sample_2”} / View CLImage cloudId={“sample_6”} / CLImage cloudId={“sample_5”} //ViewStyles for the sameconst styles = StyleSheet.create({ mainContainer: { flex: 5 }, flexOneContainer: { flex: 1 }, portraitContainer: { flex: 2, flexDirection: ‘row’}})You would have noticed that we have not given any information on width and height of the image.

Mobile devices come in multiple screen resolutions. When we display images it is important to ensure that the images displayed are optimized for screen resolution. This will ensure that images will…

Wait. What is React Native Again?

Wait. What is React Native Again?   #reactNative

  • Overall, React Native has allowed our teams to build native apps in technology we understand, using tools we know and love.
  • One of our projects involved a re-write of an existing mobile application in Cordova.
  • Not only is React Native an extremely powerful tool for developing cross-platform applications in JavaScript, it’s very easy to learn for any Javascript developer with React knowledge .
  • When using a tool like Cordova, you write the majority of your business logic and UI in JavaScript.
  • React Native is a set of tools and libraries that allows developers to write React Components that generate genuine native interfaces.

As part of our consulting process here at Differential, we often determine that a mobile app would be a good fit for our clients. Most of the time Android and iOS support is desirable, and dedicating development resources to building a native experience for both platforms is very resource intensive. We’ve skirted around this issue in the past, mostly by using Cordova, which lets us write HTML, CSS, and JS to create cross-platform apps. Cordova works great for the most part, but we discovered that you can only go so far when using web technology to create apps that feel truly native.
